Embodiment
A kind of gas-powered or pneumatic electric rotating machine in Fig. 1, have schematically been shown.This electric rotating machine comprises the rotating member 1 that is arranged in the shell 2.Pressed gas (for example air) is supplied to shell through pressed gas inlet 41, and the pressed gas that rotating member is supplied to drives and rotates.In an example shown, this electric rotating machine is the turbo-dynamo with rotor 3, but the present invention is not limited to turbo-dynamo, and for example this motor also can be the blade type motor.In addition, this motor comprises the rotatable speed regulator 4 and the connecting device 15 of the air inflow that is used to regulate the pressed gas that gets into rotating member.As noted earlier, this speed regulator can be before known type, have the moveable part that can move into pressed gas inlet 41.
Rotating member 1 comprises rotor 3 and rotor shaft 7,8, and said rotor shaft 7,8 carries said rotor and in shell 2, serves as axle journal through two ball bearings 5,6.In this connection, should be mentioned that in the accompanying drawings shell is shown as has two parts, i.e. outside 2a for bearing and inner 2b.The passage 16 that it should be understood that these parts and be used for the pressed gas of the supply within the shell can be configured within scope of the present invention in many ways.For simplicity, in specification of the present invention only with reference to as a whole shell 2.
Next, rotating member has two and extends axially shaft portion 7,8.Clutch shaft bearing 5 is installed on first hind axle part 7 of rotating member; Second bearing 6 is installed on the second preceding shaft portion 8 of rotating member; It has also constituted outstanding motor shaft, on this motor shaft, has the support member 42 that is used for rotary tool (being small gear or certain instrument load bearing equipment).Each ball bearing comprises outer collar 9 and inside race 10 and one group of rolling element 12, in Fig. 1, has only shown those rolling elements of a part that forms first rear bearing 5.The inside race 10 of clutch shaft bearing 5 is fixed on the hind axle part 7, perhaps can form with its integral body.Outer collar 9 is that axially-displaceable is moving, rotates but the ring-type friction device 13 that is arranged in outer collar and the rubber between the shell (or other suitable elastic-friction material) in the groove in the shell 2 prevents outer collar 9.In addition, have spring component 14 between lasso 9 and the shell 2 outside, on axial direction, work.Through this spring 14; The moving outer collar 9 of axially-displaceable receives direction bias voltage backward; Promptly towards the bias voltage of connecting device, thereby rubbing contact between outer collar 9, inside race 10 and the rolling element 12 and the fixedly contact angle between these parts have been guaranteed in use.
Connecting device 15 is rotatable, and is arranged as rotatablely moving of rotating member 1 is passed to speed regulator 4.Connecting device comprises the rear portion 18 of the rotatable shaft 40 that is suitable for being connected to suitable speed regulator 4.It further comprises front portion 19, and this front portion 19 is included in one group of outstanding forward on axial direction pin 11.The quantity of pin equals the quantity of the rolling element 12 of clutch shaft bearing 5, and pin 11 is suitable for contacting with rolling element, thereby plays the effect of carrying pin.Thereby the rotation of rolling element is passed to connecting device, and is passed to speed regulator 4 from connecting device.In the Fig. 1 and first embodiment shown in Figure 3, pin 11 is suitable for being inserted between each rolling element 12, thereby pin also plays the effect of the retainer that is used for rolling element.Therefore, bearing does not have any retainer.Because rolling element 12 is around the axis rotation of motor, its number of revolution approximately is number of revolution half the of rotating member 1, so rolling element 12 plays the effect of the planet wheel of planetary friction gear basically.Consequently, also can to rotate slowly than motor shaft 8 many for connecting device 5 and the speed regulator that is connected 4.Through the minimizing of this number of revolution, thus known simple ball speed regulator before can using.
Through pin 11 is provided, obtained extra Safety function on the connecting device of the effect of also playing retainer.If for a certain reason, perhaps directly through the frictional force between rolling element and the shaft portion 7, perhaps turned is crossed and is made bearing arrange or motor itself is stuck, and makes that speed regulator 4 is out of service and stops the rotation, and pin 11 can stop the axle rotation.If pin 11 has worn and torn, rolling element 12 will lose their position and lose the ability that axle is remained on correct position.Because the existence of transverse gear power and unbalanced force, axle can bear this displacement, and promptly rotary part branch with stationary part fault takes place to disturb and produce immediately.Its good effect is that motor can not exceed the speed limit if speed regulator is out of service.As shown in fig. 1, the rotation connecting device is supported in the shell 2 through suitable bearing 20,21.
Can make amendment to above-mentioned first embodiment makes it be suitable for ball bearing, and rolling element closely is fitted together in ball bearing, does not have any space that pin can insert and be used as retainer between them.For this bearing, the pin of connecting device can be shorter, to contact with rolling element, is similar to hereinafter the description about second embodiment.Be similar to this embodiment equally, this can cause obtaining Safety function.
A kind of selectivity form as embodiment shown in Fig. 1 and Fig. 3 has shown second embodiment in Fig. 2 and Fig. 4.In Fig. 2, only have only connecting device 35 different with first embodiment with clutch shaft bearing 25, the remaining part of motor is identical, thereby has identical reference character.According to this second embodiment, clutch shaft bearing 25 comprises outer collar 29 and inside race 30, one group of rolling element 32 and the retainer equipment 36 that is used for rolling element.Retainer equipment can be the general type that comprises first portion 37 and second portion 38, and rolling element is supported in place between first portion 37 and second portion 38, as shown in Figure 4.Then, pin 31 to the first embodiments of connecting device are short-and-medium, and only are suitable for contacting with original retainer equipment, and itself is not as retainer.Through this selectivity embodiment, obtained planetary effect, but can not obtain above-described Safety function.In the first embodiment, connecting device 35 will be passed to speed regulator 4 with rotatablely moving of rolling element 32.
Shown in embodiment in, clutch shaft bearing is shown as ball bearing.Yet, the invention is not restricted to ball bearing, because other bearing is possible too, roller bearing for example.
Usually, the present invention should not be considered the example shown in being limited to, and those skilled in the art can recognize easily that further alter mode within the scope of the claims also is possible.
